I am looking to make a loosely based model of the Howe's Cave Cement Pant, most likely using PVC Pipe and Gator Foam. I do not have the self expectations, nor the required room for the exact replica, so again, I am going with the "loosely based" concept. Does anyone know the "ballpark" dimensions on the concrete silos where the D&H 2-Bay cement hoppers were located? Just an idea for myself, so that I know how high to make them and if I should use 2" or 3" PVC piping.

For what it is worth, Ken Nelson wrote an article about modeling a cement plant in the July 1994 Model Railroader magazine, and I believe it was based on Howe's Cave Cement Plant. It had drawings and lots of pictures. I suggest you track down a back issue.

Ken is a good friend of mine. When I lived in Western NY I read the article as a kid and didn't think much of it. After moving to Albany and focusing on the D&H, it became more useful. Ken's model is nice too!
